“…The radiation pattern analyses at other frequencies may be carried out in future works as required. In Table 4, the performance of the proposed antenna has been compared with various antennas reported in the literature [10,13,15,16]. The simulated OMSFA [4] offers nearly 5.7 GHz wider fractional bandwidth and 7.5 dB more gain than the design in [10] while the measured OMSFA results show deep resonances covering multiple bands.…”

The simulated OMSFA [4] offers nearly 5.7 GHz wider fractional bandwidth and 7.5 dB more gain than the design in [10] while the measured OMSFA results show deep resonances covering multiple bands. It also measures at least 4 dB better gain to that of the design in [13] and 7 dB better gain than [15] in the 2.5 GHz band.…”

In this work, a 2.5 GHz fractal contoured square microstrip antenna with four ring metamaterial structure, hereon referred to as optimized metamaterial inspired square fractal antenna (OMSFA), has been presented. This paper is an extension to the previously designed OMSFA [4] and aims to experimentally verify the enhanced gain and bandwidth of this antenna. The design and simulation of the proposed OMSFA was accomplished by using Ansys HFSS (v18.2). The end-to-end antenna spread area is 23 mm x 23 mm on a 46 mm x 28 mm x 1.6 mm FR4 substrate (εr = 4.4). The simulated OMSFA was fabricated using Nvis 72 Prototyping Machine and measured in an anechoic chamber facility using vector network analyzer. The antenna resonates with the deepest return loss at S11 of -39.5 dB in a broad bandwidth of 2.53 GHz from 2.265 GHz to 4.79 GHz with experimental verification. The OMSFA provides an enhanced gain of 8.81 dB at the desired frequency of 2.5 GHz. The simulation and experimental results of resonance, gain and radiation pattern are found to agree maximally. The fractional bandwidth offered by this proposed antenna is 72.28%. The experimental validation confirms enhanced gain-bandwidth performance in a wide resonance band. Hence, the OMSFA is well recommended for wireless and energy harvesting rectenna applications.

A novel design of fractal using Giuseppe Peano geometry for wireless applications has been presented in this paper. Low cost FR4 glass epoxy substrate with 1.6mm thickness and dielectric constant 4.4 is used to design proposed antennas. The resonant frequency used for calculating the dimensions of proposed antenna is 4GHz. Three iterations of proposed antenna are designed to achieve the miniaturization. Antenna is designed and simulated by using HFSS V13 software and different parameters such as return loss, VSWR, gain has been observed and analyzed. The proposed antenna is useful for different wireless applications as per FCC standards such as bluetooth (2.12-2.95GHz), WLAN (4.82-595GHz), high speed wireless communication (5.92GHz-8.5GHz) and Xband for satellite communication (8-12GHz).
